Very nice game! Love the level design and the gameplay is really fun. I was thinking if was difficult to you too to make the enemy AI...Man, for me was tough lol Was the difficult part for me and spend a lot of time polishing that, enemy patrol withing a radius, for example. The chase was easy to do, I already did something simple on Unity years ago.
Just a small feedback about the enemy health bar, maybe it could decrease faster because, the Magician, for example, the first enemies you need only 2 shots, but seems that you have to do 3 shots, you know. Just it.
I think you did a great job!
